TUM Wildfeuer commercial 18650 VTC5A aging dataset raw mirror

BSEBench status: raw_mirror_pending_validation

This dataset is a raw mirror of the Technical University of Munich mediaTUM research-data record:

• Source title: "Experimental degradation study of a commercial lithium-ion battery"
• Source URL / DOI: https://doi.org/10.14459/2023MP1713382
• mediaTUM record: https://mediatum.ub.tum.de/1713382
• Corrected descriptive file record: https://mediatum.ub.tum.de/1734374
• Related publication DOI listed by mediaTUM: https://doi.org/10.1016/j.jpowsour.2022.232498
• Source institution / publisher: Technical University of Munich

The source record describes an experimental degradation study of 196 Sony/Murata US18650VTC5A commercial 18650 lithium-ion cells aged under calendar, cyclic, alternating, and dynamic conditions.

Provenance

Downloaded on 2026-05-08 from official TUM dataserv endpoints linked by the mediaTUM records.

• source/m1713382/: mirrored from official rsync endpoint rsync://m1713382@dataserv.ub.tum.de/m1713382/ using password m1713382.
• source/m1734374/: mirrored from official FTP endpoint ftp://m1734374@dataserv.ub.tum.de/ using the credentials linked by the correction record. The correction record's advertised rsync endpoint rejected authentication during this upload run, so FTP was used.

The source directory structure is preserved under the mediaTUM record identifiers. Source-provided checksum files are preserved:

• source/m1713382/checksums.sha256
• source/m1734374/checksums.sha512

The main source checksum file uses Windows-style path separators. For local validation only, path separators were normalized before running sha256sum -c; the normalized helper file was not uploaded. The correction record was validated with sha512sum -c checksums.sha512.

Files

• source/m1713382/: primary mediaTUM record 1713382 payload.
• source/m1734374/: corrected descriptive workbook and update readme from mediaTUM record 1734374.
• BSEBENCH_SOURCE.json: machine-readable provenance.
• SHA256SUMS.txt: SHA-256 checksums for mirrored source files and metadata files, excluding SHA256SUMS.txt itself.
